[Bug 1199059] Re: A2DP audio sink devices failed to work with "bluetoothd : Unable to select SEP" in system log.

[Erik]

This helped resolve the problem for me:

In /etc/bluetooth/audio.conf:

HFP=false
...
[A2DP]
SBCSources=1
MPEG12Sources=0

Under [General], I also added Enable=Source,Media but this may not be
necessary.
